Best Open Source Small Business Accounting Software

Since 1999 Xero has been giving small businesses control of their books by combining all their accounts in one place. Their accounting software is a cloud-based solution that allows you to get on with running your business – from invoicing to banking and payroll, to shipping and sales – all at one place combining your bank, credit card and PayPal accounts.

As small business owners ourselves, we know how difficult it can be to balance the books. We’ve spent years perfecting a cloud-based accounting suite that is easy for small business owners to use. Get all your financial data at your fingertips in real-time anywhere you are using our tools on any of your devices. Our dashboards and smart reporting make tax time a snap.



Key Highlights:

  • Personal finances manager
  • Tailored for Plasma Desktop but compatible with others too
  • Cross-platform (Windows, Linux, and macOS)

Skrooge is one of the most useful personal finances manager by KDE. It is originally tailored for the Plasma Desktop but other desktop environments are compatible.

Designed with the small-business owner in mind, Wave—which was acquired by H&R Block for around $400 million in July of 2019—prides itself on its simplicity and ease of use. Its intuitive user interface keeps the most important financial data front and center, accessible immediately after signup via any device with a web browser.

The idea here is that keeping things simple relieves much of the stress associated with accounting software. But don’t be deceived by this bare-bones approach; for a free piece of software, Wave is rich in features. This includes informative user dashboards, unlimited income and expense tracking, and customizable invoicing and sales tax processes.

Other features include:

  • Fast setup
  • Bulk transaction updates
  • Exchange rate conversions
  • PayPal, Shoeboxed, and Etsy integrations
  • Unlimited bank and credit card accounts
  • Bill and invoice reminders

While the accounting app really is free, accepting payments (2.9% + 30 cents per credit transaction, or 1% per bank transaction) and running payroll ($20 per month plus $4 per employee) are paid, optional features.

Wave also appears on our Accounting FrontRunners list for 2021.
